Chipsets:
 - Marked Intel B75 as tested
   http://www.flashrom.org/pipermail/flashrom/2013-March/010659.html
 - Marked Intel H77 as tested
   http://www.flashrom.org/pipermail/flashrom/2013-March/010607.html
 - Removed 10de:03e2 because it is apparently the MCP61 host bridge.
   It was reclassified to Host Bridge in the PCI device ID database and there
   is at least one report suggesting this configuration too:
   http://www.flashrom.org/pipermail/flashrom/2012-August/009716.html
 - Added MCP89 which hopefully works with the code for previous versions.
   Thanks to James Laird for submitting this change.

Tested flash chips:
 - Atmel AT25DF641(A) to PREW (+PREW)
   http://www.flashrom.org/pipermail/flashrom/2013-June/011113.html
 - Atmel AT25F512 to PREW (+PREW)
   http://www.flashrom.org/pipermail/flashrom/2013-April/010904.html
   Also, change its ID according to Modification of PCN SC040401A:
   "There has been a change in the returned value of the Product Identification
   (RDID) command, the AT25F512A RDID code is 65h compared to 60h from
   the AT25F512 product."
   It seems to be quite likely that all AT25F512 are fully functional relabeled
   AT25F1024 chips. There are even some hints in the datasheet:
   in table 6 they stress that address pin 16 needs to be low under all circum-
   stances; while continuous reads can wrap around on the AT25F1024 the DS
   notes "For the AT25F512, the read command must be terminated when the
   highest address (00FFFF) is reached." OTOH the lock bit semantics are
   different, but this has not been tested thoroughly

Miscellaneous:
 - Add Lenovo X201 to the laptop whitelist.
 - Add chip IDs for the ESMT F25L..QA family.
 - Add chip IDs for a few Macronix MX25 models.
 - The list of flashchips is not sorted strictly alphabetically and should not be
   either. Refine the comment explaining the scheme on top of the list.
 - Support -L output of chip sizes with up to 6 decimal places (up to 4 Gb).
 - Use z length modifier in (more) prints for size_t types.
 - Remove chips >16MB again because our current implementation of memory mapping
   the flash chip violates common rules by mapping a window as large as the chip.
   This leads to failing mmaps as can be seen here:

 - Document spispeed parameter of linux_spi (and fix some leaks).
 - Rephrase the "multiple chips detected" message because it was confusing.
 - Skip verification step if the image is equal to the flash contents.
 - Tiny other stuff.

Rename Numonyx and ST (SGS/Thomson) chips to Micron.

Micron acquired Numonyx and asked us to change the vendor names to
"Micron". For the chips clearly emerging from the former
manufacturers we (will) use "Micron/Numonyx/ST" and the original
name for the rest. Resorting the chip entries makes the diff
unreadable, hence the stand-alone commit.

sbxxx: Handle active IMCs in AMD chipsets.

Detect and temporarily disable the IMC while accessing the flash.
Disable writes on default, but allow the user to enforce it.
